Definitions

  • the location of the PEG group at the amino terminus is not particularly disruptive to the GCSF protein - GCSF receptor interaction, since the protein residues in the binding region involved in receptor interaction are not directly PEGylated or sterically hindered by the amino terminal 20 kDa PEG.
  • PEG[x]-GCSF is characterized by one or more of the following: PEG[x]-GCSF comprises less than 10% PEGx-GCSF wherein x is from 1 to 3; PEG[x]-GCSF comprises at least about 15% PEGx-GCSF wherein x is 4; PEG[x]-GCSF comprises at least about 30% PEGx-GCSF wherein x is 5; PEG[x]-GCSF comprises at least about 10%) PEGx-GCSF wherein x is 6; and PEG[x]-GCSF comprises less than 15%> PEGx- GCSF wherein x is 7. [0023] In additional embodiments, PEG[x]-GCSF comprises at least about 15%
  • PEGx-GCSF wherein x is in the range from 6 to 7; or comprises at least about 35% PEGx- GCSF wherein x is in the range from 5 to 7.
  • FIG. 4 is a representative bioanalyzer electropherogram obtained from analysis of inventive PEG[x]-GCSF samples.
  • PEG-GCSF NEULASTA ®
  • inventive PEG[x]-GCSF samples in neutropenic rats. Rats were made neutropenic by injection of cyclophosphamide (CPA) on Day -1.
  • CPA cyclophosphamide
  • inventive PEG[x]-GCSF ANF-Rho
  • NEULASTA® inventive PEG[x]-GCSF samples were administered subcutaneously at the indicated dosages on Day 1. Blood samples were obtained from the rats on the days indicated, and GCSF plasma concentrations were determined by ELISA. Data are mean and standard error for 8 rats per group.
  • FIG 8A is a linear plot
  • FIG 8B is a log plot of GCSF concentration.
  • a GCSF protein useful in the practice of this invention may be of any form isolated from mammalian organisms, a product of prokaryotic or eukaryotic host expression of exogenous DNA sequences obtained by genomic or cDNA cloning or by DNA synthesis or alternatively a product of chemical synthetic procedures or by endogenous gene activation.
  • the protein can be of a natural or recombinant source obtained from tissue, mammalian/microbial cell cultures, plant cell cultures, transgenic animals, yeasts, fungi and/or transgenic plants.
  • Suitable prokaryotic hosts include various bacteria such as E. coli; suitable eukaryotic hosts include yeasts such as S.
  • each PEG is attached to GCSF through an amine moiety originating from GCSF, for example, the N terminus, or any lysine or histidine residue.
  • covalent attachment is formed by reaction between PEG activated with an amino-reactive linker and a GCSF amine moiety.
  • the amino-reactive linker upon reaction with an amine, forms a non- hydrolysable linkage to GCSF.
  • PEGx-GCSF comprises a non- hydrolysable linkage, for example, a urethane linkage.
  • each PEG is attached to GCSF at a position selected from the group consisting of: the N-terminus, the lysine residue at position 17, the lysine residue at position 35, the lysine residue at position 41, and optionally at the histidine residue at position 44, the histidine residue at position 53, the histidine residue at position 80, the histidine residue at position 157 and the histidine residue at position 171.
  • PEG[x]-GCSF comprises a population of PEGx-
  • an inventive formulation is provided in a single dose during a course of chemotherapy.
  • the formulation is provided as multiple doses over the course of chemotherapy.
  • the formulation is administered once daily, once weekly, once every two weeks or once a month.
  • the formulation can be administered within twenty-four hours of a dose of chemotherapy.
  • the formulation is administered at least 14 days before a dose of chemotherapy.
  • inventive formulations provide much greater dosing flexibility than is the case with the commercially available NEULASTA® product.
  • the inventive formulations advantageously may be administered to a patient at any time during chemotherapy.
